9. Water pollution refers to the contamination of water bodies such
as rivers, oceans, lakes, and groundwater caused by human
activities. This can be harmful to plants and organisms which live
in these water bodies.
13. Soil pollution is formed when man
made chemicals get into the soil and
change the natural soil environment.
Oil and fuel dumping, pesticides and
underground storage units are some of
the main culprits.
22. ACID RAINS IS CAUSED BECAUSE INCREASING LEVEL OF
SULPHUR DIOXIDE AND NITROEN OXIDE IN THE AIR
23. IN 1971 BORMANN DISOVERED THAT THE
WATIER IN THE NEW HAMPSHIRE FOREST
WHERE HE WAS CONDUCTING HIS
RESEARCH WAS FILLED WITH ACID RAINS
24. MORE AMOUNT OF SULPHUR AND
NITROGEN RELEASED BY CARS AND
INDUSTRIAL PROCESSES .ACID RAINS IS
ALSO CALLED AS ACID DEPOSITION
25. HOW ACID RAIN FORMS
ACID RAIN FORMS WHEN WATER
VAPOUR AND CERTAIN ELEMENTS
COMBINE WITH MAN MADE
POLLUTANT SUCH AS NO IN THE
ATMOSPHERE FORMING SULPHUR
AND NITRIC ACID IN STATOSPHERE
26. ACID RAIN DEPOSIT IN THE FORM OF
RAIN ,SNOW IN WET CONDITIONS AND
IN DRY CONDITIONS IN FORM OF GASES
AND PARTICLES.
27. ACID RAIN AND DESTRUCTION ON CANADA
FOR THE LAST TEN YEARS ACID RAIN GOT
DESTRUCTION ON CANADA AND SOM E
PARTS OF EUROPE. IT IS THE MOST
COMMON PROBLEM IN EASTERN
CANADA BECAUSE OF LCK OF NATURAL
ALKINITY IN WATER AND SOIL SYSTEM
28. ACID RAINS FORMS WHEN OXIDES POF
NITROGEN AND SULPHUR COMBINE
WITH ATMOSPHERE. SOME OF ACID
RAIN ON HANDS
29. HOW ACID RAIN AFFECT ON FISHES
ACID RAIN FLOWS THROUGH WATER SHED
ALUMINIUM IS RELEASED FROM WATER
INTO LAKES AND STREAM LOCATED IN
WATER SHED.
30. PH OF LAKE DECREASES ALUMINIUM
LEVEL INCREASES .BOTH LOW PH AND
INCREASED ALUMINIUM ARE DIRECTLY
TOXIC TO FISHES. SO THEY BANNED
EATING FISHES IN SOME COUNTRIES
DUE TO ACID RAINS
31. ACID RAIN EFFECT ON PLANTS
acidic water dissolves the nutrients and helpful
minerals in the soil and then washes them away
before trees and other plants can use them to
grow.
32. AT THE same time, acid rain causes
the release of substances that are
toxic to trees and plants, such as
aluminum, into the soil
